  2. 1. SR-EMS Definition • Small-scale EntrySR-EMS Definition • System operating in conjunction with distribution system that has under 100kW low voltage(380V). • Economic and Efficient management system for Small-scale renewable energy sources like PV and Wind power generation. • SR-EMS Development Goal • Economic Efficiency (less than 5% compared to total cost) • SmartGrid TOC linked operation • Scalability applicable to each renewable energy power • User(Business) Management Convenience

  3. 2. SR-EMS Difference Small-scale Entry SR-EMS ProductDifference 100kWSmall-scale EntrySR System linked with low-voltage system SME ProductDemonstration by interconnecting various kinds of Power devices Economical and compact system for small-scale renewable energy Jeju Demonstration Goal Demonstration suitable for small-scale entry business model Energy storage device for stable Wind power/PVGenerationoutput Operation linked with 100kWsmall-scaleRenewable Energy Source EMS

  4. 3. Commercialization Strategy Goal 『EconomicOne-package Solution optimized for small-scale Distributed power generation』 Small-scale Wind Power+ PCS/BMS + Lithium PolymerBattery+ AVC Small-scalePV+Multifunctional PCS + BMS + *VRLA Battery • Efficient Triple junction cell Solar Battery that reformed shortcoming of Conventional siliconcell • Multifunctional PCS Use including Active/Reactive Power control and Power quality compensation function • Long life VRLA that enables cost savings over 30% • High-performance Lithium Polymer battery for stability of irregular output of Wind power generation • PCS, BMS hybridpower conditioning device and Battery management system Application • Economic**AVC for Compensation for reactive power of Wind power generation Strategy Pre condition Interoperability Standard Ensure interoperability between systems Standardization through demonstration * VRLA(Valve Regulated Lead Acid) ** AVC(Automatic VAR Compensator)

  13. 7. Business Model <Case: Renewable complex power system at Chuja Island> Target Market : Islands/rural regionandSmall areadistributed generation • In spite of high installation cost, cost and CO2 reduction by the complement of the Wind Power generation is possible. 13

  14. 7. Business Model(Continued) United States Developing Countries Target Market : Overseas SmallInterconnection/Stand-aloneRenewable Energy • Emerging Market for Smallcity/farm/public institution • - Government support for wind power installation that is under100KW • - Provide installation cost30% orunder 4,000$ tax benefit • Major position as Remote place Electrification Business by independent distributedrenewable energy source • Increasing energy demand by rapid economic growth countries like China, India, Brazil • - Renewable energy independent power system to supply energy • -Dynamic promotion both securing resources andDevelopment of Renewable energy • Unique alternative Under situation like High oil prices, Greenhouse gas emissionreduction pressure

  15. 8. Conclusion Strength of Korea Electricity Korea Electricity Industry One of the biggest energy-consuming countries in the World Relatively new power infrastructure & Superior ability of operation “World Best” power qualities - Outage hour in Korea : Just 14.29min/year(France : 57min/year, UK : 68min/year, USA 122min/year) • Loss rate of transmission/distribution in Korea : about 4% (UK : 9%, USA: 7%, JAPAN : 5%) Korea was selected as a leader in Smart Grid technology at 2009 G8 Summit! Power IT Infra : Young and already SMART Related IT Convergence Industry “World Best” of Korea IT infra  “IT KOREA” • Broadband internet deployment ratio : World’s #1(95.9%, OECD 2009) • Builds the world’s first nationwide Smart Grid system currently • Jeju Smart Grid Test-bed : World’s largest Smart Grid community “World Best” smart home appliance, automobile, EV, construction, and shipbuilding
